I don't use my cruise control for my daily commute, because in my daily commute, I have familiarity with the roads and the traffic and can manage my speed/mileage better myself that way. Also, even though that daily commute is interstate driving, it is near Boston, so the traffic speeds are not super consistent for cruising anyway. On the other hand, I found cruise control very helpful on a road trip I just got back from - I had five or four passengers so the acceleration of my Hybrid Civic was quite significantly dampened, and I was on interstate highways nearly the whole time, for long stretches that I wouldn't have wanted to be doing without cruise control anyway. I did tend to use the accel and decel buttons quite a lot, adding to the 'video game' aspect of the driving, to match my speed with the rest of the traffic and so forth. I also think it helped because I wasn't used to how my Civic performed with so much weight in it, so I would have had difficulty driving it for efficiency as well as I do when I'm alone. I may begin using cruise control for more of my commute, we'll see.
